I don't know what % concentration Phosphoric Acid C-Dan-D-Luxe was able to purchase overseas, but in the USA you cannot buy full strength (85%) unless you have a registered business that requires the use of it. Despite its very weakened use in soda, that's why a spill screws up your auto paint finish , at full strength it is extremely corrosive and requires copious amounts of water to flush away.Despite what he says and I know he means well, skin contact can damage the nerve endings, fume overexposure can damage your lungs, and obviously you can lose your sight even with protective googles if they don't fit right. I won't even get into what flushing it away does to the environment.
Okay. I'm off my horse. They're must be a safer commercial product available.
